Who builds Whop Payments for WHMCS

I'm George. I build and maintain Whop Payments for WHMCS, the free module that connects WHMCS to Whop, and I run this site.

Who I am

The module is published by my company, G&S DIGITAL SINGLE MEMBER P.C., a Greek company. I build it, write its documentation and answer support messages myself.

The module is tested on WHMCS 8.13.7, 9.0.7 and 9.0.8, all on PHP 8.3. A walkthrough on a fresh WHMCS 9.0.8 install verified Sandbox payments, a 3D Secure challenge, a partial refund and a staff alert for a Whop Resolution Center case.

What the module does

Whop Payments for WHMCS lets your customers pay WHMCS invoices through Whop. One install adds two gateways: Whop Payments for cards and saved-card renewals, and Whop Checkout for one-time payments with the other methods Whop offers your business.

WHMCS keeps your invoices, tax, credits, reminders and provisioning. Whop's job is narrow: it collects the payment, holds the balance and pays you out.

What this site is for

This site answers one question: which payment gateway should a WHMCS business use, and how do you set it up? My answer is Whop. The download page has the module, and the documentation (opens in a new tab) covers every setup step.

Why I recommend Whop

Whop fits the way a WHMCS business bills its customers.

  • A domestic card payment costs 2.7% + $0.30, with no monthly fee, per Whop's fee schedule as of September 2026.
  • A Whop business can be based almost anywhere. Whop excludes only a short list of countries, mostly ones under sanctions.
  • Saved cards become native WHMCS Pay Methods, so WHMCS's own cron collects renewals on its own schedule.
  • Whop Checkout adds the other methods Whop enables for your business, such as PayPal and wallets, with no separate integration for each.

The home page makes the full case for why Whop is the best WHMCS payment gateway.

How the module is funded

The module is free and adds no fee of its own. Whop pays me a partner commission out of its own revenue when you create your Whop business through the sign-up link in the module's settings. Whop's processing fees apply to every payment, as with any Whop business.

Whop Verified Partner

G&S DIGITAL is a Whop Verified Partner. Create your Whop business through our link and you can message us for help.
